fix(homepage): clean up GSAP DOM classes on perspective toggle

useGSAP's ctx.revert() only cleans up GSAP-managed inline styles,
not imperative classList additions. Add cleanup function to remove
stale arrow-line/arrow-head 'active' and row 'row-match'/'row-dim'
classes when isDev changes, preventing visual glitches on toggle.
